What are the advantages of using Distance Vector Routing ?

Advantages of Distance Vector Routing are :



  1.  Large Routing Tables
  2. High network traffic overhead.
  3. Route advertising is done periodically even after the internetwork has converged.
  4. Multiple routes to a given network ID can be reflected as multiple entries in the routing tables.
  5. Doesn't scale.

Disadvantages of Distance Vector Routing are :

       1. It is slower to converge than the link state.
       2. It is at risk from the count-to-infinity problem.
      3. It creates more traffic than link-state since a hop count change must be propagated to all routers and processed on each router. Hop count updates take place on a periodic basis, even if there are no changes in the network topology, so bandwidth-wasting broadcasts still occur.
     4. For larger networks, distance vector routing results in larger routing tables than link-state since each router must know about all other routers. This can also lead to congestion on WAN links.

Show that number of pendant vertices in a binary tree is (n+1)/2 ,where n is the number of vertices in the tree.

The number of vertices of odd degree in an undirected graph is even,(N-1) is even.  Therefore, n is odd. Let p be the number of pendant vertices. 2+p+3(n- p-1) = 2(n-1) or, 3n-2n-3+4 = 2p or, 2p = n+1 or, P = (n+1)/2 Hence, the number of pendant vertices is (n+1)/2. Also, see : 1.)  Graph Theory and Tree 2.)  The Reflection about line yx is.......... 3.)  Prove that a simple graph with n vertices and k components can have at most 1/2(n-k)(n-k-1) edges. 4.)  Show for what condition rotation and scaling are commutative. 5.) Vector in R space 6.) Prove that every tree has at most one perfect matching. 7.)  Prove that every tree with 2 or more vertices is 2-chromatic. 8.)  Show that every Bi-partite graph is 2 chromatic. 9.) Prove that the number of circular permutations of n different objects is (n-1)! . 10.)  State the "Pigeon Hole Principle" and the " Generalised pigeon Hole principle".

Prove that every tree with 2 or more vertices is 2-chromatic.

Image
Since a tree is connected and has no cycle if one starts coloring any one vertex with a specific color and keeps on coloring every alternate vertex with another color, the entire graph can be colored with only two colors and since there is one and only one path between any two vertices in a tree, no two vertices will have the same color. Hence every Tree with 2 or more vertices is 2-Chromatic.    [Proved]                                                                 FIG (I)                                                                  FIG (II)

Top 5 websites to learn coding Online

Now, A Days Technology became our Daily Life partner. Sometimes we people are wondering how this page, website, Blog ,Game works .Then,Our Mind  starts searching for Real phenomenon .How this site works ,why this website is different from others,How the widget is different from others ,How e-commerce website works. So, The answer of all of the above is "CODING". Being a programmer ,i think without Coding Digital Word is Nothing. So, you need to learn Coding if you are interested in Digital world. Myths about coding is that It is Hard to Understand & Hard to Write.There is nothing like this.Just you have to do some basic Homework daily and continuation in learning.Learn Coding like a Interesting Puzzle and solve like a "SUDUKO" Game. Let's Start: Kids Section: For kids Go for  Tynker   (Android/IOS) and  Hopscotch   (IPAD) .These sites are the best tutor of kids ,they teach coding in the form of Games & Puzzles.
